Product descriptions are key, however over-explaining will be your worst enemy and will make your customers less likely to read if there is a huge paragraph with little detail.
You need to make your audience imagine themselves with the product. For example if you are selling a candle then you can set the scene of having a glass of wine laying on the couch with a lovely candle burning. Using creative language will let the reader be able to imagine themselves already with the product.
For a younger audience it could be that you’re selling a clothing line and talking about what pieces could be great for upcoming festivals. An amazing example of a company with great captivating product description is Charlotte Tilbury.
This is because even though they have a lot of text they make it fun to read with bold words and lovely phrases. They talk about their product features while setting the scene of how luxurious it is to use their product and the features it has.
